An enjoyable way for children to memorise the colours of the rainbow. This delightful colouring book, with beautifully hand drawn pictures on single sided pages, creates a step by step creation of the rainbow with each rainbow page preceded by the written name of the next colour to be added. Within each of the seven rainbow pictures there is a hidden Secret Key for the child to find and colour in too. Once the rainbow has been "built" there are word pages to colour in and groups of animals, insects, trinkets, vegetables and fruits featured within the book.
